A new Instagram bug is causing users to lose followers, sometimes millions of them. The glitch has affected celebrities including Kylie Jenner, Justin Bieber, Kim Kardashian, and Ariana Grande, who all lost more than a million followers. It has also come for influencers, who have seen their follower counts plummet by the thousand.

When the bug was first noticed, many assumed it was another crackdown on fake accounts, but this appears to have been an accidental purge.

“We’re aware of an issue that is causing a change in account follower numbers for some people right now,” Instagram wrote on Twitter. “We’re working to resolve this as quickly as possible.” In a follow-up tweet, the company assured users that the issue will be fixed later today, February 14, by 9 a.m. PST.
